- Little Pend Oreille River Natural Area Preserve (dnr.wa.gov)
Located in northeast corner of Washington, this preserve includes a large expanse of wetland habitats and adjacent conifer forest along the Little Pend Oreille River. The mosaic of wetland habitats, including areas dominated by a variety of shrubs interspersed with extensive open marshes, provides excellent habitat for waterfowl, osprey, moose and many other wildlife species. Two state-listed sensitive plant species, poor sedge and bulb-bearing water hemlock, are also found in the open marsh areas on this 290 acre preserve.

If we look into the source code of the first person shooter Doom we find that the value of pi used in the game is wrong. In this talk I will explore what happens when we subtly and not so subtly break math in the source.
